To all whom it may-concern. I

,Be it known that 1, JOHN B. BARTHOLO- MEW, a citizen of the United States, residing at Peoria, in the countyof Peoria and State of Illinois, have invented certain new and useful 'Improvements in Cultivators, of

which the following is a specification, refertools and for readily adjusting their positions to meet varying requirements. 7

Figure 1 is a plan view of an implement embodying my improvements. Fig.2 isa side elevation of the same.

7 A cultivating implement is illustrated as an entiretj and although some of the parts are well known I will briefly describe them in order that a complete understanding may be had of the improvements to which this invention more particularly relates.

a '11 indicate the ground wheels upon which-are supported the framework and the operative parts. "These are mounted upon a crank axle 2 havin the top horizontal bar 3, and a downward y depending crank part 4. The latter are turned outward at their lower ends to rovide supports for the wheels there being cast brackets at 5 se axle the'latter being adapted to rock in the connecting devices; and at their other ends the side bars. are joined to a cross bar 23 upon which also rests the rear end of the tongue 7.

In cultivators of, this sort-- The'crank axle is held in one position or another in relation to the frame by means of a cross crank shaft 10, the parts 11 of which are connected to the lower parts of the crank axles by the links 12, the latter being plvoted to inwardly extending lugs 13 formed on the castings 5. To the crank shaft there is connecteda lever 14 there beng a bracket interposed between them and indicated by 15, this bracket having downwardly turned arms which by means of'U- bolts at 16 are connected to the cranks 11. At 17 there is a ratchet segment with which engages the spring-actuated detent 18 controlled by the hand latch 19. This lever extends backwardat an; inclination so that .it can be readily reached by the driver when riding in the seat at 20 which is connected to. the supporting strap 21 adapted to be ad ustably fastened atone point or another along'the frame bars 6 by the setting devices 'By means of the lever 14 and the, devices connected therewith the wheels can be ad justed forward or backward under the main frame for the purpose of compensating for one side of the longitudinal center of the machine to the other. At the lower ends .of this, arched bar are attached the cultivating and scraping devices. "In the machine shown 'there are two of these scraping or' cultivating blades at each side of the machine as shown at 26. They are arranged on lines inclined to the line of draft and each is inclined from its edge outward and backward. Each is connected toa standard 27 which extends up to and is secured in a carrying bar 28. Each of the scrapers or shovels is secured to its standard by a plate 29 with an car 30 which is clamped'to the bottom of the standardv 27 by a bolt 31. Each of the standards is formedwith' a curvature at 32 which permits the scraper or blade to be normally adjusted to the angle desired.

The carrier bar 28 is hinged at 33 by a vertical pivot to a plate 34 secured to the lower end of the arched bar and arranged substantially horizontally. This platehas a rearward extending part 35 provided with ratchet teeth 36. To the bar 28 which carries the blades there is secured a rearwardly extending lever 37 having a spring dog and lever 38, the dog being adapted to engage with the teeth at 36. By means of these devices last referred to the carrier bar 28 can be adjusted in one position or another correspondingly adjusting the angle of inclination of the blades 26 to the line of draft.

operator control of their vertical position.

42 is a bent stirrup rod connected to a hook at 43. 44 is a chain or flexible suspending device connected by a rod 45 to the lower end of a spring 46' interposed between the rod 45 and; the upper hooked ends of the bent stirrup rod 42. 47 is a hand lever pivoted at 48 to the main frame'and having its short arm 49 connected .to the chain or sus-' pension device 44. 50 is a ratchet segment and 51 is aspring-actuated detent on the hand lever 47. i I

By means of the devices last described the operator can set the hoes or scraper blades vertically at any desired position. At the same time there will be possibility for the blades to rise or descend if they require it, and the operator while in his seat can,

with his foot in the stirrup at 40, cause the blades to move downward or upward as he sees fit. Furthermore, the operator can, with his feet, move the tool carriers 28 laterally and cause the tools to follow the row of plants with great nicety, this free lateral movement of the tool carriers being possible by reason of the manner in which they are supported from the main frame.

With implements'of this sort I have found it very desirable to frequently var the angle of the hoes or blades to the su ace of the ground it being desirable to have them at times run more deeply and at others less. To enable the operator to quickly effect such and adjustment of the cutting angle of the blades I provide the lever 52 which is mounted well forward on the tongue at 53.

Its short arm is connected by long links 54 with the carrier. bar 28 for the hoes. Each link 54 at the bottom has a bracket plate 55 to which it is rigidly connected and this plate in turn is hinged at 56 to the hoesupporting bar 28.

By varying the position of the lever 52 the operator can cause the bar 28 and the hoes to move back and be suspended in such a p'ostion that the hoes will be more sharply inclined to the surface of the soil and, vice versa, by moving the lever in the opposite direction it will, through the links 54, draw the hoe carriers forward so that they will be in positions where they will be inclined at relatively smaller angles to the surface and will not tend to cut so deeply.

A median'or normal adjustment of the angle of the hoes or blades is secured by means of the clamping devices at 57 and the slot 58 in the bracket 55, which permits the link 54 to be set at one angle or another as the occasion requires, and after that the operator still has a wide range of control through the lever 52 which can be locked in onev position or another by the detent and segment 59.

60 indicates a covering or smoothing blade arrangedto follow the scraper blades or hoes 26. It is held by bars 61 which extend backward from the carrier bar 28 and by intermediate link bars 62 adjustable, in relation to the arm '61 by means of rose plate connections at 63 and the blades 60 being adjustable in relation to the link bars 62 by arose plate connection at 64.
